THE BIOTRANSFORMATION OF SOME STEROIDS BY CEPHALOSPORIUM APHIDICOLA
Hanson, James R.,Nasir, Habib
, p. 831 - 834 (2007/10/02)
Hydroxylation of 5α-androstane-3-one and 3,6-dione by C. aphidicla takes place at C-17β and, in the case of the latter, at C-5α.The fungus reduces 5α-androstan-17-one and the 3,17-dione to the 17β-alcohols. Key Word Index - Cephalosporium aphidicola; fungus; microbiological hydroxylation; steroids.
Antenna-initiated photochemistry in polyfunctional steroids. photoepimerization of 3α-(dimethylphenylsiloxy)-5α-androstane-6,17-dione and its 3β isomer by through-bond exchange energy transfer

We have previously reported that photolysis of 3α-(dimethylphenylsiloxy-5α-androstane-11,17-dione, in the presence of triethylamine (TEA) and with 266-nm light so as to selectively excite the dimethylphenylsiloxy (DPS) "antenna", primarily gives rise to t
